Description

General part information

NCP4687 Series

The NCP4687 is a CMOS 500 mA LDO linear voltage regulator with high output voltage accuracy which features a high ripple rejection, low supply current with low dropout and chip enable with built in low RDS(on)NMOS transistor for fast output capacitor discharging as option. The device is composed of the voltage reference unit, error amplifier, resistor divider for output voltage sensing or precise output voltage setting. The current limit and thermal shutdown makes the device very suitable for industrial applications and portable communication equipments.
